A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram, rather than the rectangle that is the plan view of a regular, or "square" arch. In the case of a masonry skew arch the construction requires precise stonecutting as none of the cuts form right angles but once the principles were fully understood in the early 19th century it became considerably easier and cheaper to build a skew arch of brick. The problem of building skew arch masonry bridges was addressed by a number of early civil engineers and mathematicians, including William Chapman (1787), Benjamin Outram (1798), Peter Nicholson (1828), George Stephenson (1830), Edward Sang (1835), Charles Fox (1836), George W. Buck (1839) and William Froude (c. 1844).

Famous quotes containing the word arch:
“Men themselves have wondered
What they see in me.
They try so much
But they can’t touch
My inner mystery.
When I try to show them,
They say they still can’t see.
I say,
It’s in the arch of my back,
The sun of my smile,
The ride of my breasts,
The grace of my style.
I’m a woman
Phenomenally.
Phenomenal woman,
That’s me.”
—Maya Angelou (b. 1928)
